Spring Security 3.1 - Automatically redirect to login page when session-timeout occurs

Question

I have a wenb applicatoin based on Spring and I am implementing Spring Security 3.1.

What I need is to be able to automatically redirect to login page, when the configured session-timeout occurs. I am implemting web pages containing a lot of jQuery functionality, so I need to be able to automatically redirect.

What currently happens, when the session-timeout passes, it's not until an action is performed - page submission that it redirects to the login page.

my spring-security.xml:

<http auto-config="true" disable-url-rewriting="true">
    <intercept-url pattern="/test/user*" access="ROLE_USER, ROLE_ADMIN"  />
    <intercept-url pattern="/test/admin" access="ROLE_ADMIN"  />
    <form-login login-page="/test/login" 
            default-target-url="/test/home" 
            authentication-failure-url="/test/loginfailed" />
    <logout invalidate-session="true" logout-success-url="/test/logout" />
    <!--
    <session-management invalid-session-url="/test/login">
        <concurrency-control max-sessions="1" error-if-maximum-exceeded="true"/>
    </session-management>
    -->
</http> 

And in my web.xml I have:

<!-- Web Session Timeout (mins) --> 
<session-config> 
    <session-timeout>10</session-timeout> 
</session-config>

I don't think you will need to do it yourself, Spring pretty much handles this itself. That's the greatness of Spring!
